Three batteries in parallel means three times the connection points, three times the chance of imbalance, and three times the cabling. One 280Ah unit is cleaner, simpler and electrically more efficient. 1Lower Internal ResistanceA single large cell has lower internal resistance than multiple smaller ones in parallel. Less resistance means less heat, less voltage drop and more usable energy under high loads. 2Space and Cable SavingsOne battery box, two terminal connections, one cable run to your inverter or controller. In an RV battery compartment or under a deck, the space saving is significant. 3No Parallel Imbalance RiskBatteries connected in parallel can develop voltage imbalances over time if cells age differently. One battery eliminates this entirely - one BMS managing one cell group. 3,360Wh SINGLE UNIT CAPACITY 15,000 MAXIMUM CYCLE LIFE 200A PEAK DISCHARGE CURRENT WHAT 3,360Wh ACTUALLY RUNS Enough stored energy to run a full home through the night - and then some. At 85% usable capacity (2,856Wh), a single 12V 280Ah unit delivers serious runtime on real home and RV loads.

Bluetooth 5.0 MonitoringConnect via Bluetooth 5.0 to the ECO-WORTHY app. Monitor SOC, voltage, current, temperature, remaining capacity and cycle count in real time from your phone. Up to 15,000 CyclesGrade-A LiFePO4 cells with a cycle life ceiling of 15,000 at shallow discharge depths. At one cycle daily that is over 41 years. At 80% DoD you still get 6,000 cycles. Low-Temp Cut-Off ProtectionBMS stops charging automatically below -20 degrees C to prevent cold-weather cell damage. Discharge continues safely. Essential protection for outdoor and cold-climate installations. 160A Continuous / 200A Pulse160A continuous discharge supports large inverters and high-draw loads. 200A pulse handles motor startup surges from pumps, compressors and inverter-driven appliances.

Solar PanelsTo recharge a 280Ah battery daily you need approximately 400-600W of solar. A 600W array at 5 peak sun hours gives 3,000Wh per day - matching the usable capacity of this battery.View solar panels MPPT Charge ControllerSize to your panel wattage. For 600W at 12V you need a 50A or 60A MPPT controller minimum. Ensure it has a LiFePO4 charge profile for correct voltage settings.View MPPT controllers Pure Sine Wave InverterWith 160A continuous discharge, this battery can run a 2,000W inverter at full load.

How long does this battery take to fully recharge from solar? At the recommended 40A charge current, a full charge from empty takes approximately 7 hours. In practice, your MPPT controller regulates charge current based on available solar power. A 600W panel array in good sun conditions (5 peak hours) delivers around 3,000Wh per day – enough to fully replenish the usable capacity of a 280Ah battery in one sunny day. On overcast days or in winter months at higher latitudes, factor on partial recharge and plan your loads accordingly. Is 280Ah enough for a full-time RV setup? For a well-managed RV electrical system – LED lighting, 12V compressor fridge, device charging, water pump and a diesel heater – 280Ah is a solid single-battery starting point. At around 200W average draw you get roughly 14 hours of runtime at 85% DoD. If you run air conditioning regularly or have high AC loads through an inverter, consider two units in parallel for 560Ah. As a general guide: 100Ah suits weekend campers, 200Ah suits regular campers, 280Ah suits full-timers and boondocking setups. Can I run an air conditioner from this battery? A 10,000 BTU window AC unit draws approximately 1,200W continuous. At 85% usable capacity (2,856Wh) this battery gives you around 2.3 hours of runtime on AC alone. That is enough for sleeping hours if solar recharges during the day. For extended AC use, connect two or more batteries in parallel and ensure your inverter is sized for the startup surge – AC compressors can pull 3-4x rated watts on startup. The 200A pulse rating handles this. What solar panel size do I need to fully recharge this battery in one day? To replace 3,360Wh in one day (assuming you discharged to 85% DoD), you need your solar array to produce at least 3,000Wh of net energy after controller losses. In a location with 5 peak sun hours, a 600W array delivers roughly 3,000Wh per day. In locations with fewer peak sun hours, or for winter use, size up to 800W-1,000W to reliably recover a full charge in shorter days. Use an MPPT controller sized at minimum 60A for a 600W array at 12V. Can I connect this battery in series to make a 24V or 48V system? Yes. Two units connected in series give you 25.6V 280Ah (7,168Wh total). Four units in series give 51.2V 280Ah (14,336Wh total) – a 48V system. Ensure all batteries in a series bank are the same model, same capacity, same age and in the same state of charge before connecting. Series connection increases voltage while keeping capacity the same. Parallel connection keeps voltage at 12.8V while doubling or tripling the Ah capacity. Why does this battery stop charging in cold weather? The BMS includes low-temperature cut-off protection that stops charging automatically below -20 degrees C (-4 degrees F). This is a safety feature – charging LiFePO4 cells below freezing causes lithium plating on the anodes, permanently reducing capacity and potentially causing a short circuit over time. Discharging can continue safely at these temperatures. If you install this battery in a cold-climate environment, consider insulating the battery box or using a self-heating battery model for very cold winter applications. How does the Bluetooth monitoring work and what does it show? Download the ECO-WORTHY app on your iOS or Android device and pair via Bluetooth 5.0. The app shows real-time state of charge as a percentage, current voltage, charge and discharge current in amps, remaining capacity in Ah, cell temperature, cycle count and estimated remaining runtime at current draw rate. You can also view fault history and protection events. Bluetooth range is approximately 10 meters. The app does not require an internet connection once paired. What inverter size should I pair with a 12V 280Ah battery? The 160A continuous discharge rating means this battery can safely power an inverter drawing up to approximately 2,000W continuous at 12V (160A x 12.8V = 2,048W). The 200A pulse current handles inverter startup and motor surge loads. For a full RV or cabin setup, a 2,000-3,000W pure sine wave inverter paired with this battery gives you enough headroom for most simultaneous loads. Running a larger inverter is possible but you may hit BMS protection limits on heavy continuous loads. Delivery and Returns Expedited US and EU shipping available. This is a heavy item at 28.5kg.
